BAG-LOCK.

To all whom it may concern:

Be it known that I, PHILIP A. Mlonm, a citizen of the United States of America, residing at. New York city, in the county of New York and State of New York, have invented new and useful Improvements in Bag-Locks, or which the following is a specification. I

The invention aims to provide-as its pr ncipal object a device of the character embodying a casing with which there is associated a flexible engaging member. One end of the flexible member being secured to the casing while the other end thereof is slidable through the casing and engagea'ble by a locking member carried within the casings. Unique means is provided for disengaging the locking member from the flexible member when releasing the latter, and this means-is engageable by a key, so that suitable combinations can be formed whereby each look can be so made as to be operated only by a particular key. a

v The further object of the invention is the provision of a. device of this character which is simple in construction, durable and efl'eetive in operation and inexpensive to manufacture.

Other and further objects appear in the following description wherein the invention is setforth in detail.

As shown and described, a specificjembodiment isadhered to, but to thisembodiment the invention is restricted. The right is reserved to make such alterations an changes as reduction of practice may suggest, in. so faras such changes or alterations are compatible in spirit with the annexed claims.

I'n'the accompanying drawings: 7

by which the locking member is moved to lock or unlocking position. A Fig. 7 is a, perspective view of the combination plate whereby the lock may be made operable by a specified shape of key only. Fig. 8 is a plan view of the key used with the particular combination shown. 7

As shown, the invention comprises a flat hollow casing 1, on certain of whose side walls there are formed projections 2 in which there are formed holes 3 for the reception of suitable rivets by means of which a cover. forsecuring the casing to house within the operating membersof the lock. This coveris not shown in Figs. 1 and 2,but the lower portion thereof in which there is formed an aperture forming a bearing for the key barrel appears in Fig. 3. .Pivotally carried upon a pin 5 which is fixed in the "front wall of the casing 1- and also in the that it may have one edge lie adjacent to one of the side walls of the casing. This side wall. designated? i rouglhened on its inner face, and thatedge of t e-locking member adgacent this inner face is formed with a shallow groove 8 of' curved formation inv cross section. V

The casing 1 of the interior is formed with a lug 9. and this lug has fixed in it one end of a flat bodied spring 10, the free end of the latter bearing against one end of the locking member 6; and tending to; keep its grooved edge 8 forced over toward the roughened inner face of the side wall 7 the casing 1. A flexible member 11 has one end passed through an appropriate hole formed in the top side wall of the casing 1 and through a registered hole in the lug 9, this end, of the flexible member interior to the casing being knotted as shown at 12 so that the flexible member may ,not be withdrawn from the casing. ,At the opposite end of the interior end wall of the casing a second hole 13 is formed through which the other end of the flexible member 11 is admitted to the casing. This other end is designed to pass down through the easing and out through i the bottom wall through a hole 14, the portion lying within the casing being engaged by the groove edge 8 of the locking member 6, and forced over against the roughened inner face of the wall 7. The pivotal pointof the locking member'G, it will be observed, is nearer the top of the casing than is that part of the locking member which engages the flexible -member 11. Therefore, any pull tending to draw the flexible member out of the casing when it is engaged by the locking; member only tends to tighten the engagement of the the flexible member irrespective ofany irregularitie of diameter of the latter.

. The locking member 6 is formed with a depending tail portion 16, which is slotted transversely to receive the end of a pawl 17. This pawl and locking member being plyotally connected together by means of a'pln 18, as shown. The bottom edge'of the pawl i pawl 17. "Adjacent'one' end of the bar 24 is formed with a plurality of teeth 19, which are designed for engagement by the teeth'20 carried upon a key barrel 21, the latter being pivotally mounted in the front wall of the casing '1, and the cover member 4 of the latter; This key barrel is formed with a radialslot 22 extending throughout its length and this slot is designed to receive a key .23, by whichthe key barrel is turned and its operation effective.

Fixed upon the bottom wallof the casing there is a bar 24 whose upper edge is formed with the teeth 25 designed for engagement with the terminal tooth 26 formed on the andadjacentalso to the barrel 21 there is an angular ward plate 27, which" is secured to the bottom wall of the casing, and so positioned that its upstanding portion which is slotted infthe peculiar fashion shown at 28 may v describe the shape of key necessary to operate the barrel. v

A flat spring 29 is fixed in the member 6, and its free edge bears on top of the pawl 17 and tends to "keep the latter forced towardand in engagement with the teeth 25 on the bar 24. p

In the operation of the improved lock, the locking member 6 when in locked position, stands as shown inFig. 1, and the end 26 of the pawl 17 engages between the two teeth 25 nearest the left. The barrel stands as shown with a vertical slot, and its teeth 20 just to the right of the last of the teeth 19 on the pawl. The elongated or oval shaped slot 15 in the locking member enables the springlO to retain the locking member in a locking positionwhere theflexible member 11 will be forced firmly againstathe roughened face of the side wall 7, and the flexible member is thus prevented from being withdrawn from the casing. To release the flexible from the flexible member with the flexible member, the key 23 is inserted in the barrel after which the latter is moved angularly by turning the key, the slotted portion 28 of the ward plate 27 corresponding to the shape of the operating end of the key permitting the key. to pass and the barrel to be turned thereby. The operating, end of the key, designated" by 30, after the barrel has been turnedthrough approximately 180 degrees encounters the teeth of the pawl 17 slightly raising the latter and tending to force it and the connectingend ofthe locking member 6 toward the right. So soon as this end 30 of the key has moved far enough to disengage itself with the teeth of the pawl 17 the teeth 20 of the barrel engage with the teeth 19, r

and the pawl is thereby-continued on its movement to the right, this operation swinging the locking member 6 on its pivot stud I 5 so that when the terminal tooth 26v rests between the two-teeth 25 nearestthe right the locking member will be swung away and that end of the flexible member which the locking member previously engaged may be withdrawn through the casing.

It is'obvious that theflexible membermay be drawn taut around the necks or bags of same articles to lock them in closed position, and the peculiar construction fofthe' device makesit serviceable for a hand cufl" or for any other purpose where a flexible locking member may be ofservice.

From the foregoingdescription and. the accompanying drawings, it is believed that a clear-enough understanding of the invention is to behadto render further description unnecessary;

The invention having beende'scribed what is claimed as new and useful is:

1. A lock-of the character described comprising a casing, a flexible memberfhaving one end secured in the casing and-extended to form a loop, the remaining endhaving a sliding engagement with the casingpa p1vcarried otally mounted locking member; within the casing and having'an edge engageable with the running'end of the flexible member to force the latter against one a spring tending to forcev wall of the casing, the locking member into suchengagement member, a key barrel pivotally mounted in the casing, a pawl pivotally connected with the locking member, a

, bar carried in the casing and having teeth engageable by the pawl, the pawl being formed on one edge with teeth, the barrel also being formed withteeth, and a key by which the barrel is moved angularly, the key first engaging the teeth of the pawl and the teeth of the barrel thereafter engaging the pawl, whereby the locking member is swung to unlocked position against the pr'essure of the spring. a

2. A look of the character described comprising a casing,

a flexible member having one end secured to the casing, and the other end in runnlng engagement with the casing,

a cam shaped locking member pivotally 5 mounted in the casing and having one ed e engageable With flexible member the running end of the said to force the same against one side Wall of the casing, a key barrel rotatably mounted in the casing, and operative connections between the key barrel and the 10 cam shaped locking member for the useful purpose specified.

In testimony whereof I aifix my signature.
